For example, consider an elevator. When the fourth-floor button is pressed on the first floor, the elevator rises to the fourth floor with speed and floor-leveling accuracy designed for passenger comfort. The push of the fourth-floor button is an input that represents our desired output. Control theory has played a vital role in the advance of engi…
